The grandfather to Hau. He is the Kahuna of Melemele Island and a member of the Alola Elite Four. He specializes in Fighting-type Pokémon. He grants the Melemele stamp to Trainers who defeat him.

Ho! I have been expecting you. Allow me to properly greet the young adventurers embarking on their island challenge. I am Hala, the kahuna of Melemele Island. Shall we begin? The final trial here on Melemele Island will be a Pokémon battle against me, the kahuna! It is known as the grand trial!

The moon in the daytime... The sun at night... Now to see if you can pour your heart into something that cannot be seen but is very much real. As you continue on your island challenge, consider what makes up the people and Pokémon that you meet: both what you can see and what you cannot.

The Trial Captain of Melemele Island's Verdant Cavern. He specializes in Normal-type Pokémon.

Greetings! Captain Ilima here. I couldn't help but observe your battles. You looked so very delightful in battle that I had no choice but to summon you here.

What an incredible Trainer you are! For you to be able to defeat the Totem Pokémon that I had trained up to such a powerful state... I don't know what I can say!

What you have just received is the Normal Z-Crystal! It is known as Normalium Z! Now if you let a Pokémon that can use a Normal-type move hold that... and strike an elegant pose like this one... then you will be able to strengthen a Normal-type move by unleashing Z-Power!

The Trial Captain of Akala Island's Lush Jungle. She specializes in Grass-type Pokémon.

Hey! Thanks for stopping by! I'm Mallow, one of the captains here!

Thanks for stopping by! Welcome to Lush Jungle, the trial grounds for me, Mallow! I knew it the first time I saw you and your team... You've chosen only the finest ingredients! That's why I'm gonna make you help me—er, no! I mean, that's why you should try my trial! You are the one who got a Sparkling Stone straight from Tapu Koko, aren't you? You're so totally ready for this! Ah, the breath of the jungle... I can tell just what today's special should be...

What? What's wrong with you guys? Don't you have any taste?! Are you headed off to Olivia's for the grand trial?!

One of Professor Sycamore's assistants, and often appears along with another assistant, Dexio. She specializes in Ice-type Pokémon.

Stop right there!

My name's Sina! A beautiful name for a beautiful lady!

The item that I just gave you is for collecting the Cores and Cells of a Pokémon—Zygarde. I'll tell you the details another time, so please keep it safe for now. For your island challenge, it might not be a bad idea to go to Route 4 to train your Pokémon. We'll be taking our leave now! Bon voyage!

The Trial Captain of Akala Island's Brooklet Hill. She is described as an expert with Water-type Pokémon who is dedicated to her family and a reliable older sister who watches over her younger sisters.

Hello. I'm Lana. I serve as the captain of Brooklet Hill. You look like an able-bodied Trainer. Could I ask for your help with something?

Oh my... So it was Wishiwashi kicking up all that water? Even a little Wishiwashi can make such big waves...

Brooklet Hill... Within it lies the Legendary Pokémon said to be the embodiment of the sea itself... the mighty Kyogre.

The Island Kahuna of Poni Island. She specializes in Ground-type Pokémon.

You there, Trainer. Can you come to my aid? Over here. These scoundrels are Pokémon thieves. And you’re on familiar terms with them? I am Hapu. Life in the big city sure is something else. Pokémon thieves roam about brazenly...

Glad to see that one will get home on her own. I’ve got you to thank for that. Give me your name, Trainer. David, eh? That’s a fine name. I like the way you handled yourself in battle. Mudsdale and I are always wandering all about Alola to try to achieve our goals, so perhaps we’ll meet again someday. I am indebted to you for your aid, after all. Ah yes. You might want to try your hand at a Battle Royal or two, David. Mudsdale here thinks you’d be well suited to it, given how strong you are.

I give my thanks... for your great blessing. As kahuna, I will do my best for the people... and the Pokémon of Alola.

I am Kiawe. My Marowak and I are students of the ancient dances that have been passed down in Alola for generations.

My trial will test your powers of observation! There will be a dance...and then another. Your task will be to find the difference between the two. Begin!

The Firium Z...you should show it to the Trial Guide outside the captain's barricade at the bottom of the mountain. It is time for us to return to our dance. The feelings of the Alolan people and our Pokémon, and the true nature of Z-Power... The answers lie in our dance! And so we must dance on!

Are you interested in success, dear readers? Then allow me to introduce myself. My name is F, and I am an elite, self-made man. Here on my blog, I will show you the way to succeed.

Currently I am working on the development of a special sort of ball, which I took over from my predecessor, in parallel with another project. Seeing how well I multitask impresses my subordinates and increases their motivation. Showing how skillful you are is a kind of on-the-job training for your underlings.

I once ventured to undertake a project without notifying my superior. I developed a device to restrain a dangerous life form, in case it became necessary to do so. I had it made for hedging risks to protect myself, but for better or worse, it was made public. It is always essential to consider the risks before one takes action.

The assistant branch chief of the Aether Foundation's Aether Paradise.

I have to tell you how much I appreciate what you did for Miss Lillie and Madam Lusamine. Miss Lillie asked me a last favor before she left. She wanted me to explain to you why she and her mother had to go to Kanto. You see... while we do not know if it was because of Nihilego's neurotoxins, her fusion with that beast, or the strain of the Z-Power... the ill effects of this episode on Madam Lusamine's body and mind have been undeniable. She has hardly roused since.

The UBs surround themselves with an aura called the Beast Boost. The truth of this aura is that it is the energy that flows within the Ultra Wormhole. When the UBs pass through the Ultra Wormhole, they are bathed in a great deal of this energy and likely store it within their bodies. There are also Pokémon on our planet that possess this same kind of energy. I think you know what I mean. The so-called Totem Pokémon that you faced in your trials. This is because the energy pours down upon our planet when the holes open.

The Admin of Team Skull. She is considered the "big sister" of the team, due to how she runs operations strictly but also cares for her underlings. She specializes in Poison-type Pokémon.

So, you're the one Gladion was talking about? ...Hmph. You don't look like anything special to me. I'm Plumeria. I help keep Team Skull together. I'm like a big sister to all there numskulls. You have realized what idiots all there guys are, right? But don't you think some dummies are cute in their dumbness? You know what I mean, right? You picking on my cute, dumb brothers and sisters is really annoying me!

That's enough. No one wants to see a sore loser.

You know... deep down, you're kind of like the president. You've gone in a different direction, but I can tell you have the same strength in your convictions. Bring Guzma back, if you can. I know you've got no reason to help... but no one can make up for what they've done if they're gone.

Ah... You must be David and Hau. Welcome to Aether Paradise. The Aether Foundation's own private island. I am the president of the foundation. But please, just call me Lusamine. I’m so glad that we got to meet. I'm glad there are people like you, who travel the islands to learn more about Pokémon... But there are also those unfortunate people who harm Pokémon for their own selfish reasons or even for profit. And that is why I am here. I will be like a mother to all of those poor Pokémon and shower them with love. Even Pokémon from distant worlds, far from the Alola region, are worthy of my love.

My... You do say such incomprehensible things. Calling me mother? I don't have any children! Certainly not any wretched children who would run off and reject my love! So tell me how you'll save that Pokémon. What can you do, Lillie? You failed to convince me to listen to you. You don't even have the strength of a Trainer. The only thing that you've ever done on your own is steal someone else's research material! You're not beautiful enough for my world... but fine. Since you're here anyway, you can watch me summon my sweet beast. And then... you can leave.

Enough with this useless talk, Lillie! I will never forgive you for stealing Cosmog from me. Never! Back when you were small, you would listen to everything I said, without question. For a time, even you were adorable to me! But you changed. You’ve become ugly. Ever since you met this boy, David... and learned to defy your own mother! David! You hateful little Trainer! How dare you intrude upon this world that was meant for Nihilego and me? It is not to be borne! And with Nihilego’s power, I will show you how wrong you were to come here!

A Pokémon Researcher in Alola. He studies the regional variants of the region. He is a cousin of Professor Oak, with whom he shares a striking resemblance.

Why, hello there, Rotom! Are you feeling nice and comfy there in that Pokédex of yours?

Oh! Well, hello there. Good to meet you. I'm Oak—Samson Oak. I'm a Pokémon researcher, and I'm looking into the regional variants found around here. And you must be David, huh? Young Kukui mentioned you to me.

The Trial Captain of Thrifty Megamart's abandoned site on Ula'ula Island. She is also a Ghost-type Trainer and a member of the Alola Elite Four.

Is this what you're looking for, Princess? Give it a read!

David! You made it through Sophocles's trial, huh? That's really great! You can take on the next trial up past Route 11. Through Tapu Village, you know? If you get lost on your way, ask a police officer for directions. They're here to serve, right?

What's that? You say the Poké Finder just started up on its own, during your trial? Oooh, cut it out, David! You're trying to scare me, huh? You'll have to come up with something a bit more believable than that! There's not even any room in the back of that shop, for starters! How gullible do you think I am?

It's David, right? Thanks for coming all the way up Hokulani to visit us. But our Captain Sophocles is a busy young man. Always calculating comets' paths or working on that Festival Plaza thing of his...

The Trial Captain of Ula'ula Island's Hokulani Observatory. He specializes in Electric-type Pokémon.

You're getting close to your goal... I imagine that you must have come here to attempt the trial, huh?

You summon the Totem Pokémon and prove your strength to it... That's what every trial boils down to, right?

So I thought... Why not just call the totem here from the start? So I tried a bit of this and that, and I think I've whipped up a little device to call the Totem Pokémon. Perhaps you're wondering why I built a machine? Here at the observatory, we also monitor sounds that we detect from outer space. There are some sounds that are inaudible to people but Pokémon can hear just fine. We broadcast the sounds we have gathered terrestrially and monitor the reactions of Pokémon. The machine that summons the Totem Pokémon makes use of this technology... Utilizing other sounds we have gathered, we also developed a security system here... But that was actually Big Mo's invention. Just so you know... This will actually be my first time trying it out, so I'm glad you came. I needed a test subject.

You there, boy. Seems to me you're trying to get into Po Town. You sure you've thought this through? You'd better be ready if you’re thinking of coming in here. Ready to live as Team Skull. Or ready to take on Team Skull. You really think you're ready for that?

You there, boy. I'm an island kahuna, you know. Battle against me. It'll be a good experience for you if you're really hoping to master the island challenge.

Well, shoot... Of course I already knew you had the heart and the strength to storm Team Skull’s stronghold, but I didn't know you were this good. And your Pokémon worked real hard for you. Let me fix your team up for you.

The Trial Captain of Poni Island. She specializes in Fairy-type Pokémon.

Oh! Now that's a great composition! I could paint a picture of you—the visitor to Poni! Guess I didn't introduce myself though. I'm Mina. I'm the captain. I mean, I sort of am. I actually just wander around doing my art, so I don't have an actual trial or anything... But Vast Poni Canyon sure is a wonder, huh?

Hallo! They sent me here on an errand. Since I'm not busy doing trials or anything. It's a secret. Oh, and I had one more order I was given. Or was it a request? Either way... I was told I should have a real serious battle with David before I came back. I don't really know why, but it seems like maybe it's some sort of trial of strength.

Oh! The one from the great composition! Looks like you've beaten everybody else in this place, huh? Then have a battle against Captain Mina! Let's get our Z on! I hope you're ready for the extraordinary Z-Power of me and my Pokémon!

So, here you are... Why don't we see who the winds favor today, you...or me?

My name is Kahili. A few years ago, I was a champion of the island challenge, too. Just like you. I've been traveling the world to improve my skill as both a Trainer and as a golfer. When I heard that they'd made a Pokémon League in my own home region, I came flying back to serve Alola. Have a look at my fantastic Flying-type team!

You know...I think you'll bring a breath of fresh air to the Alola battle scene. I was honestly annoyed when Kukui kept pestering me to come here, but I'm glad I did.

The former Frontier Brain in charge of running the Battle Frontier's Battle Tower.

It is an honor to meet you, of course, the first Champion of Alola. Please forgive our rude summons. My name is Anabel. I am the head of a secret division within the International Police. We are the UB Task Force.

The UBs are the beasts... otherwise known as Ultra Beasts. They are unidentified life-forms that reside in a different world from the one we live in. That Nihilego creature you encountered was one such beast.

Ryuki is a musician who has traveled to Alola from another region beyond the sea in order to spread his fame. He's also one of the Trainers who challenges the player for the title of Pokémon Champion.

The name's Ryuki. I'm what you might call a star. I mean, with partners like my Pokémon, how could I not be a star? I came all the way across the sea here to Alola to spread my fame out here, too! The whole world will be mine soon!

Everyone's got their own problems, huh? The critics loved my songs, but nobody was buying my music for a while, man. But I'm just a rocker down to my bones. Nothing else to do but keep on rocking. I dig you, Champ. Looks like you know who you are, too, right down to your bones.
